Edges appear jagged in Render

Dear community,

I am fairly new to rhino and seems like there should be an easy solution but I can’t find it. When I create multiple tubes/ cylinders next to eachother (solids) they appear jagged in my render (vray).(see image) Why does it seem like its made up of polygons? And is there any way to increase the resolution? Preferably without increasing the amount of subdivisions since I tried that and it slows down my PC to much. Hope anyone can help.
